Spatial distribution characteristics of human activity intensity in Libo County

摘要

The spatial distribution characteristics of human activity intensity in Libo county are studied in three aspects, including the total distribution characteristics, the distribution characteristics of each township and the spatial autocorrelation analysis based on the calculation of the human activity intensity of the villages and towns in Libo County, which is proposed by Xu Yong et al. The results showed that the overall human activity index in Libo county was low, and the highest level was only 10.8%. The spatial distribution pattern of human activity intensity is generally characterized by low south and low north, showing a tendency of low, low, medium, high and high distribution from southeast to northwest. The intensity of human activities in the villages and towns has significant global spatial agglomeration (positive correlation) characteristics, the concentration pattern is high (HH) and low (LL), and most of the areas have no obvious agglomeration mode, showing obvious local spatial negative correlation type. The concentrated area of high value is concentrated in the northwest part of the town of Jia Liang and Fang village. The low value agglomeration area is distributed in the southeast of the world natural heritage distribution area and the national natural protection area, mainly concentrated in Dong Tong Township.
